We’ve had this for a couple months now, so I feel like I can give a full review. My girls’ allergies are so bad here where we moved, and since we started using this humidifier, we’ve been having WAY less bad days of sneezing and runny noses. I feel like it also allows them to get quality sleep. It’s especially helpful if they have any cold like sniffles. Love love love! Will continue to use and recommend to all.
